SOURCE: M y radio stopped working on my 2004 trail blazer

The 2004 Trailblazer has two fuse panels, one in the under hood and one under the middle row seats. The radio fuse is marked RADIO fuse # 41 and is a 15 amp fuse located in the rear fuse panel. To access the rear fuse panel flip the seat behind the driver to the upright position, under it you can see the fuse panel and a diagram should be on the under side of the cover. 

Good luck and hope this helps.

ok it is going to be either the people who replace the a/c compressor might overcharged the a/c system with too much refrigerant or you throttle need to be clean, ask the shop to clean your throttle or go to autozone and buy a throttle cleaner and do it your self , of course if you know how to, but if not autozone might give you some advise, and if this two did not resolve your problem ,then replace the idle control motor, or also known as iac vlave, or iac motor, good luck and let me know but the most important is your feed back to me, and excuse the delay but my business is groing up and just been extremelly busy.

you have a trouble code stored. This means the pcm has detected a problem somewhere

SOURCE: How to do I reset

there is no light for emissions testing on this vehicle. there is a ses light that can come on, indicationg a problem with the engine or transmission electronic system. this will require a scan tool to pull trouble codes. there is another light called oil life monitoring that needs to be reset after oil changes, which I suspect is what you are seeing. here is a picture of the light and the instructions for resetting.,

The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE OIL SOON message being turned on, reset the system.
After changing the engine oil, the system must be reset as follows:

1. Turn the ignition to RUN, with the engine OFF.
2. Press the information and reset buttons on the Driver Information Center (DIC) at the same time to enter the personalization menu.
3. Press the information button to scroll through the available personalization menu modes until the DIC display shows OIL LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you the system has been reset.
5. Turn the key to LOCK.

I take it, it comes on while you're not engaging 4WD. If so, I'd check the micro-switch on the gearbox. Make sure the connection is good and its not dust gumming up the works.
